A Proposed Methods for the Design of Thin-walled Beams which Buckle Locally

Explicit expressions for the local buckling of a generally imperfect, simply supported plate are used to develop a simple method for the design of thin-walled beams. Comparison with test results for lipped-channel beams shows that the method gives good agreement with both collapse asymmoments and elastic deflexions.
